FTP

• proftpd
  • Create a ftp user and group

proftpd

• By default proftpd use system users and passwords in /etc/passwd for login;
• We can create virtual ftp-only users as well, which is accomplished by using the ftpasswd command;

Create a ftp user and group

1. Create the user and group, use the uid and gid of default webserver user (33)

   cd /etc/proftpd/
   
   # create a group
   ftpasswd --group --name ftpgroup --gid 33
   
   # create a user
   ftpasswd --passwd --name wordpressuser --home /var/www/wordpressuser_home/ --shell /bin/false --uid 33 --gid 33

2. Make sure the output files ftpd.passwd and ftpd.group are readable by the ProFTPD user (proftpd by default);

3. In the config file /etc/proftpd/proftpd.conf:

   RequireValidShell   off
   
   # only use the following files for auth, do not use system users (mod_auth_unix.c)
   AuthOrder mod_auth_file.c
   AuthUserFile /etc/proftpd/ftpd.passwd
   AuthGroupFile /etc/proftpd/ftpd.group
